Question

In a circle of radius $6$ cm, a chord of length $10$ cm makes an angle of $110$ ${}^{\circ }$ at the centre of the circle. Find the area of the circle.

Answer 1

$\Rightarrow$ Radius of a circle $=6cm$ [ Given ]

$\Rightarrow$ Area of a circle $=\pi r^2$

$\Rightarrow$ Area of a circle $=\frac{22}{7}\times (6{)}^2$

$\Rightarrow$ Area of a circle $=\frac{22\times 36}{7}=113.14c{m}^2$
